Not all of the planets within our solar system have a magnetic field. Venus and Mars are the only ones that don't have a magnetic field (all other planets do have one).
yes all the other planets have magnetic fields except venus because it rotates to slowly
No. Earth's magnetic field only affects earth, not other planets.
The planets within our solar system that have a magnetic field are: Earth, Jupiter, Mercury (though it is weak), Saturn, Neptune, and Uranus.
Mars has gravity, as do all planets, but not a magnetic field.
All planets have magnetic fields. I believe that in most cases, this magnetic field can act as a shield.
other planets
Yes, they most definitely are.
Other planets
I assume you mean "planets". Yes, other planets have magnetic fields, too. Jupiter, for example, has a very strong magnetic field.
Only planets that have an active iron core. Only planets with a magnetic field
Neptune, Uranus, Saturn, Jupiter, and Earth all have magnetic fields. Mercury has a very weak magnetic field.
